Debunking the Myth: The Truth About Skin Hydration and Drinking Water
For those striving for hydrated and glowing skin, a surprising revelation awaits: Contrary to popular belief, consuming water does not directly hydrate dry skin, as explained by esthetician Renée Rouleau.
Rouleau, whose clientele includes Demi Lovato and Lili Reinhart, recently addressed the prevailing misconception on Instagram, labeling it as the top skin hydration myth: the idea that drinking water leads to moisturized, plump skin. Contrary to common belief, Rouleau claims that water consumption is actually “the least effective method to hydrate the skin.”
This may sound startling, but the science behind it is sound.
In simple terms, the water we consume follows a complex biological process and doesn’t have a direct route to reach the skin cells. Rouleau explains that after passing through the intestines, entering the bloodstream, and being filtered by the kidneys, water primarily hydrates the internal cells of the body. It doesn’t effectively reach the outer skin layers, known as the epidermis. Skin hydration is more dependent on the sebaceous glands and skin barrier, as noted by dermatologist Dendy Engelman, MD, based in New York City.
It’s a lot to digest, but hold off on abandoning your water bottle just yet. While water may not be a panacea for skin hydration, it remains vital for the proper functioning of organs, tissues, and lymphatic systems. The interconnectedness of these systems means that staying hydrated impacts your overall appearance. Adequate hydration aids in reducing puffiness and optimizing skin circulation, contributing to a radiant complexion.
For achieving plump, moist skin, Rouleau recommends focusing on topical hydration through skincare products. Look for products containing hyaluronic acid (HA), a molecule that attracts and retains water effectively. Many essences, such as H2O+ Priming Water Essence ($40), provide ample HA without adding weight to your skincare routine. Incorporating HA into your sunscreen can also be beneficial; consider products like Peter Thomas Roth Water Drench Hyaluronic Hydrating Moisturizer SPF 45 ($52) or Neutrogena Hydro Boost Water Gel Sunscreen SPF 50 ($10).
Another key ingredient to seek out is glycerin, often paired with hyaluronic acid in skincare products. Glycerin is a potent humectant found in water-based creams like Belief The True Cream Aqua Bomb ($52) and Simple Water Boost Hydrating Gel Cream Face Moisturizer ($4).
The takeaway here is that while drinking water may not directly hydrate the skin, it is essential for overall health and well-being. When it comes to achieving supple, hydrated skin, incorporating topicals like hyaluronic acid and glycerin in your skincare routine is key.
